Abstract
A microprocessor-based static converter control circuit includes a free-running counter which is synchronized with the powerline phase and frequency using a zero-crossing detector circuit. Firing angle commands are received and converted to a corresponding firing count. The microprocessor outputs a firing code for the thyristor firing pulse circuit when the count of the free running counter reaches the firing count.
